Application led June 20, 1921.

To all whom t may concern:

Be it known that I, FORTUNATO GIOMMI,

a subject of the King of ltaly, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Incubatore, of which the following is a specification.

My present invention has reference to an incubator.

My primary object is to produce an improved heating and Ventilating system for incubatore.

A still further object is to produce an incubator in which the incubating chamber is provided on the interior of a water circulating jacket, a packing being arranged between the exterior of the jacket and the outer body of the device, a dead air chamber being provided between the top of the incubating chamber and the body, means being arranged between the incubating chamber and the exterior of the body for admitting a circulation of air into the incubating chamber, valved means being also provided which serve as an outlet for foul air from the compartment, while in addition to this for humidifying the warm air in the incubating chamber.

The foregoing, and many other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which iorm part oit this specification.

in the drawings Figure 'l is an elevation of the improvement.

Figure 2 is a top plan View thereof.

Figure 3 is a sectional view on the line 3 3 of Figure 2.

Figure 4 is a sectional view on the line 4 4 ot Figure 2.

Figure 5 is a horizontal sectional view ap- 45 proXimately on the line 5- 5 of Figure 1.

Figure 6 is a detail sectional view on the line 6-6 of Figure 4.

Figure 7 is a horizontal sectional View through a slight modification, in which the body and water jacket are round in cross section.

The body of my improved incubator is in the nature ot a substantially rectangular box-like structure and is broadly indicated by the numeral 1. The body 1 is supported at its corners on legs 2.

Serial No. 479,022.

In the body 1 there is a water circulating jacket which includes a bottom portion 3, sides 4 and ends 5. The side and end walls 4 and 5, at the top ot the jacket are connected. together by plates 6 which close the hol low interior of the said acket. rlhe substantially rectangular hollow water jacket is oit a less size than that ot the body 1, and the space between the said water jacket and body receives therein a packing of some suitable non-heat conducting'material. The interior of the water jacket provides the incubating chamber and is, for distinction, indicated by the numeral S. Resting on the bottom 3 of the incubating chamber 3, adjacent to either the side or end walls thereof are upwardly extended members 9 provided at spaced intervals with transverse cleats 10. The cleats on one of the members 9 are disposed directly opposite the cleats on the opposite member, and these cleats provide supports ior the reticulated egg frames 11. One or a number ot such frames may be employed in accordance with the number' of the chicks to be hatched, and preferably each frame is provided with means whereby the eggs thereon can be turned for the well known purpose.

Resting on the closed top of the water circulating drum and on the top of the packing 9 is a plate 12 This plate is provided with a central opening 13 which is closed by a transparent plate 14. lThe plate 12 provides what I will term the inner top member for the incubating chamber, a second plate 15 being arranged on the upper edges oit the body 1, and providing a dead air space 1G between the same and the plate 12. rllhe plate 15 is also provided with a central opening that is closed by a transparent plate 17. Preferably the plates 14 and 17 are received in frames that are suitably supported on iianges formed on the walls provided by the openings in the said plates 12 and 15, and consequently, the transparent plates serve as means whereby the eggs in the incubating chamber can be inspected, and also as doors whereby access can be obtained to the interior ot said chamber. rlhe cover plate 15 has arranged thereon handle members 18, and similar members maybe arranged on the inner cover plate 12, or it' desired this last mentioned plate may be hingedly connected to the interior ot the body.

The inlet :for the Water jacket is indicated Jill@ tubes are preferably four in number andv also preferably comprise lsectional members, that is an outer member which is telescoped i in an inner member, the outer member lia-ving its passage controlled by a valve which is operated by a stem 21. The tubes 2O provide the outlet for foul air from the `incubating chamber. y

Fresh air is let into the incubating chamber through tubes 22 thatv are arranged adjacent to the `floor of the incubating chamber. Preferably fou-r tubes 22 are arranged in spaced relation through each of the sides and le-ndsof the water jacket, the `said tubes also 4passing through the packing 7 and through the body 1.

The bottom of the body is, for distinction, indicated by the numeral 23, the packing 7 of course, 'being arranged between the bottom of the body and lthe bottom .ofl the water jacket. The bottom 23 is centrally provided with a notched or cut-away portion 24, the packing being likewise cutaway, but being retained lin proper position by angularly disposed plates 25 that provide walls for the opening 24. The plates 25 also support a plate 26 :that is in contact with the lower wall ofthe water jacket. This plate 26 is n direct contact with heat which is admitted from a heater 27 suitably sup.- ported rby means 28. rllhe heater may be in the nature of an ordinary lamp, a gas or gasoline stove, or any other' desired means capable of generating sullicient heat to retain the water 29 in the acket ata temperature desirable for incubation. In this connection, it is to be stated that one of the important features of the construction is the fact that the water druiniis surrounded on its sides, ends and bottom b y the nonheat conducting packing 7 and its top is protected by the dead air space 30 provided between the cover plates 12 and 15. As a consequence, should the heater 27 be eX- tinguished even for a reasonable period, the ywater in 'the jacket will not vbecome sufliciently cooled to impair' thextemperature in the incubating chamber.

The bottom of the jacket `is provided with a valved outlet spout 31 that passes through the bottom of the body, the valve 32, controlling the passage ofthe said spout being, of course, arranged `eiiteriorly of the body.

During the process of incubation, have found it to be desirable, if not essential that the warm air be humidiiied, and to accomplish this, I connect to the water jacket, ad-

jacent to the top thereof a comparatively small tube rlhe tube is arranged adjacent to one of the sides or one of the ends of .the jacket, .extending downwardly against said side or end and having on its lower portion a horizontal branch 34C provided with radially disposed minute apertures. The outer end .of the Abranch 34 is closed, and the passage of the pipe 33 is controlled by a valve 35 arranged in close proximity to the doors provided by the transparent plates in the cover-plates 12 and 15.

lt is believed that the foregoing description, when taken in connection with the drawings will fully set forth the fconstruction and advantages of the improvement,

and that further detailed Idescription will not therefore be necessary. It is to be stated, however, that the nature of the invention is such as to render the same susceptible to various changes in size, proportion, material employed, and in details of construction, and therefore l am not to be limited to the device as set forth in the specification and Aillustrated by the dra-wings, but am entitled to all such changesv therefrom as fall within the scope of what is claimed.

It may be found preferable to construct `the body, or at 'least the water jacket of hollow members which are round in cross `section, such yconstruction being illustrated in Figure 7 of the drawings. In the said figure, the body is indicated by the numeral 1'., and `the water jacket by the numeral 50. Except in shape, the details of the construction are similar to that previouslydescribed. While space in the cylindrical construction is sacriced .it is believed that a more uniform heat will be produced in the incubating chamber, and zthe structure, as hereto- .fore inferred merely illustrated to indicate a modiication which may be employed.

Having described the inventioinclaim :H

,. V,ln an incubator, a leg supported body, a 1

box-shaped water jacket in the body, a nonheat conducting packing between the water j acket and the body, said body and packing having aligning openings at the bottom thereof, a plate ,engaging lower wall .of the jacket in a line with said openings, a heater ldepending from said bottom and the upper portion thereof being arranged between the means at the top of the jacket for the admission of water therein, valved means at the bottom of the jacket providing .an outlet forthe water, the interior of the jacket providing an incubating chamber, means for 'removably supporting reticulated egg trays c therein, a plurality of tubes arranged in iio openings for heatingthe water in the jacket,

1,4343@ ggg ranged above the st mentioned plate and resting on the upper edge of the body, and valve controlled Jfoul air outlet pipes carried l0 by said plates.

In testimony whereof l allx my signature.
